Title: Sportster
Post by: jsachs1 on January 10, 2018, 03:34:46 PM
My '86 Snortster I built in '89. 1200 cc.
Set 2 Dragbike Natl. records, made the cover of Thunder Alley magazine Jan. 1995, and a few other magazines and softcover books.
I raked the frame, built a 4" over swing arm with air in crossmember for the air shifter. Used a PM rear wheel with a 160 X 18" rear tire. I made an offset front sprocket, to keep chain alignment in check. Akront 18" narrow front rim and small tire. I painted the body parts my traditional orange pearl, and had it lettered in gold leaf.

I like it John, I always thought Sportys looked fast just sitting there. I've only owned one in my life, a 1974 XLCH. AT 6' 6" tall when I was younger (I've shrunk), my knees were in my arm pits riding one.

Very nice. That's how Sportsters should be. I still have that magazine. Wish they still published it.

Maybe I missed it but what did you run in the 1/4?

Eleven 0's at 124. As pictured.
When I sold it the buyer had me build a wheelie bar for him. He's been in the 10.60 range. That was back in 1996. He still owns the bike.

That is very cool. A proper Sportster, IMO. Makes me really miss my old '94. Mine was a good bit milder, only doing 12.90 at 105 at a test & tune night at Rockingham, but still a whole lot of fun.

Makes me want another Sporty to hoon around on again.

John you may get even more responses if you post a picture of the back of that bike so more people can recognize it.  :wink:

That sure brings back memories, thanks for the post.

:up: Thanks, Vic.
I built a customer a clone to it in 1992. It made American Iron Magazine in 1999. Quoted " This bike is far ahead of its time."

Very nice John!!
11.0 @ 124mph tell's me its making 10 second power!!
what was your 60 ft times?
also how many cubic inch? & what carb?

I'm in Australia been drag racing street Harley's off and on for years had a kick start shovel late 70's stock frame no wheelie bar, foot shift ratchet lid 4 speed 98 inch stock shovel heads done by my friend Cow, ran 11.7  114mph ( that shovel still going )
then had 2001 dyna tc88 (95) stock frame foot shift I road it sometimes 600miles to the track then road it home. I was tuning 11.28  best speed was 121mph but the times and speed would change with track or weather ( 60ft times too ) that bike still going
got an old carb Buell cyclone, but have not raced that.
then last year got a 2003 XLH1200 I bought it off a lady who lives up Far North Queensland, flew up, road it home to New South Wales ( good ride!! )
then as the stock 1200 carb ( low miles ) no go, I picked up Axtell cast iron 88" barrels flat top pistons, also got new 2017 heads, getting my friend to resize cases, check flywheels go through gear box. I'm thinking set up at 10.0:1 RS 630/585 as I like strong torque.
I have a Bobby Wood Rebel 43.5 & Hammer Sledge 3" air cleaner ( cycle shack tampered end one piece duels ( old man ) plan is bulk Torque & make HP & TQ as quick as I can only want to rev to 6,000, I know you are good with heads!! I'm thinking use stock size valves just better quality and set up for the lift. what do you think? ( when I dyno it, we will time how quick it makes HP & TQ I'll take the tune that makes HP & TQ the quickest so not shooting for all out HP )
sorry for long post you could pm me if like.

jsachs1, fantastic!!
I was around in those day's when there was no over the counter parts like now.
Kawasaki clutch, would have needed lot of time to set up. I bet you broke a lot of 4 speed gear box's!
I remember back in old day's in Australia. we raced on an old air strip, no traction , time slip was written down just ET & Trap Speed.
but no easier to race a motor bike at drag strip today, just you get more information to see where you can improve. but still hard thats why I love it!!
well done!!
